Abstract

The embodiment of the invention discloses a multi-ECU wiring harness connection method and a wire harness control box. The method and the wire harness control box are used for connecting multiple ECUsto achieve multi-wire-harness normalization, and improve the portability of multi-ECU connection. The method includes the following steps that an MCU is used for detecting whether a wire harness is connected with an electronic control unit (ECU) or not; if yes, the MCU detects the type of the ECU and receives the ECU types input through an ECU selection button; according to the ECU types, the MCUcontrols a drive circuit and a switch array, so that a corresponding communication signal and a switching signal are in a conducting state.

Description

technical field [0001] The present application relates to the field of ECU detection and control, in particular to a multi-ECU wire harness connection method and a wire harness control box. Background technique [0002] When the automobile manufacturer inspects the ECU of the production vehicle or upgrades the ECU firmware, it needs to select the correct wire harness and connector between the inspection equipment and the ECU. For example, when connecting the ECU of the first type, the first wire harness and the first connector need to be connected with the ECU, while when connecting the ECU of the second type, the second wire harness and the second connector are needed for connecting with the ECU. [0003] In this way, the following disadvantages will result: [0004] When there are many kinds of ECUs, wire harnesses and ECU connectors of various specifications are required. Usually, the sizes and specifications of wire harnesses and connectors are large. On the one hand, t...
